Police got a confession from Kristi Lyn Bateson nine years after her husband was found shot to death while she was shopping. Tests showing her emotional vulnerability helped overturn the verdict.

On an April morning 18 years ago, Kristi Lyn Bateson dressed her two small daughters for the hourlong drive to Mount Shasta Mall. Her husband, Charlie, was sleeping after his graveyard shift at the sawmill.
